Well, to be perfectly clear about what I have, I do have a JDM Version 9 Spec C engine, combined with a USDM Sti current generation intercooler.

The current generation intercooler is the biggest Subaru has fitted on any car.

This may still be relevant to the growing community of JDM EJ207 American Owners, as well as to the people that have chosen to upgrade their OEM intercooler to the biggest possible OEM intercooler, the 08+ Sti.

Also, David from Synapse is helping me already with my missing parts, so things are starting to look better.

With this said, I think I may be able to fix this by grinding the ribs on the OEM BPV Elbow at the bottom of the valve, I think it's wedging there and I only need 1/4" or less.
